| Abstract [eng] |
Construction and demolition waste (CDW) is the largest in both weight and volumetric waste stream in Europe, accounting for about 25-30% of all waste, which is more than 500 million. tons per year. SGA is one of the priority waste streams in the EU. As stated in the EU Circular Economy Action Plan, many of these substances are either recyclable or reusable, but the extent of reuse and recycling varies considerably between the EU Member States. 2008 November 19 Directive 2008/98 / EC of the European Parliament and of the Council on waste provides for measures to protect the environment and human health. In order to achieve the objectives of this Directive, Member States must take the necessary measures to achieve, by 2020, at least 70% (in assessing the amount of waste) non-hazardous construction and demolition wastes other than the naturally occurring substances in category 17 05 04 of the waste list would be prepared for reuse, recycling and other uses, including filling operations using waste instead of other materials. Some of the Member States have already reached or even exceeded their target, while others, including Lithuania, are on their way. The aim of this work is to investigate the need and possibilities for increasing the processing of construction and demolition waste (CDW) in Lithuania. The work consists of three sections: 1) analysis of the situation and experience of the management of construction and demolition waste; 2) research methodology; 3) results. The first chapter examines the emergence of CDW in the European Union, the environmental impact of CDW, the challenges for CDW management in the European Union, the practice of CDW use, technological and managerial solutions used in different countries, CDW recycling in Lithuania. The second chapter reviews the research methods. The paper uses scientific literature, informal interviews and comparative analysis methods, forecasts for the formation of CDW flows and needs. The bases and registers of the environmental protection agency, data of the Lithuanian Geological Survey. The third chapter analyzes the situation of non-hazardous flow of concrete, tiles and ceramics (BA) in Lithuania, the formation and maintenance of CDW in Lithuania. The legal regulation was analyzed, the use of recycled concrete, methods for improving the quality of sorting. BA supply and demand analysis, SWOT analysis performed. Depending on the results of Lithuania's situation and the experience of other countries, offers of recycling opportunities for secondary raw materials (concrete, tile and ceramics) are offered. |
